ORIENTATION: Enterprise resource systems have not always led to significant organisational enhancement and many projects in which these systems have been implemented turn out to be over budget, not on time and unsuccessful. RESEARCH PURPOSE: The aim of this study was to test the technology acceptance model within a South African SAP^® Enterprise Resource Planning user environment MOTIVATION FOR THE STUDY: No study could be traced in which the technology acceptance model has been evaluated in the South African context. RESEARCH APPROACH, DESIGN AND METHOD: A cross-sectional survey design was used. The 23-item Technology Acceptance Model Questionnaire was deployed amongst SAP^® Enterprise Resource Planning users (N = 241). MAIN FINDINGS: The results confirmed significant paths from perceived usefulness of the information system to attitudes towards and behavioural intentions to use it. Furthermore, behavioural intention to use the system predicted actual use thereof. Perceived ease of use indirectly affected attitudes towards and behavioural intentions to use via perceived usefulness of the information system. PRACTICAL/MANAGERIAL IMPLICATIONS: Practitioners should build user confidence by ensuring the ease of use of a new system, providing relevant education, training and guidance and reiterating its usefulness and future added value to the user's job and career. CONTRIBUTION/VALUE-ADD: This study contributes to scientific knowledge regarding the influence of individuals' perceptions of information system usage on their attitudes, behavioural intentions and actual use of such a system.
